+==== Voice Settings
+
+ {application} provides voice announcements during
+ flight so that you can keep your eyes on the
+ sky and still get information about the
+ current flight status. However, sometimes you
+ don't want to hear them.
+
+ Enable::
+ Turns all voice announcements on and off
+
+ Test Voice::
+ Plays a short message allowing you to verify
+ that the audio system is working and the volume settings
+ are reasonable
+
+==== Log Directory
+
+ {application} logs all telemetry data and saves all
+ TeleMetrum flash data to this directory. This
+ directory is also used as the staring point
+ when selecting data files for display or
+ export.
+
+ Click on the directory name to bring up a
+ directory choosing dialog, select a new
+ directory and click 'Select Directory' to
+ change where {application} reads and writes data
+ files.
+
+==== Callsign
+
+ This value is transmitted in each command
+ packet sent from TeleDongle and received from
+ an altimeter. It is not used in telemetry
+ mode, as the callsign configured in the
+ altimeter board is included in all telemetry
+ packets. Configure this with the {application}
+ operators call sign as needed to comply with
+ your local radio regulations.
+
+ Note that to successfully command a flight
+ computer over the radio (to configure the
+ altimeter, monitor idle, or fire pyro
+ charges), the callsign configured here must
+ exactly match the callsign configured in the
+ flight computer. This matching is case
+ sensitive.
+
+==== Imperial Units
+
+ This switches between metric units (meters)
+ and imperial units (feet and miles). This
+ affects the display of values use during
+ flight monitoring, configuration, data
+ graphing and all of the voice
+ announcements. It does not change the units
+ used when exporting to CSV files, those are
+ always produced in metric units.
+
+==== Serial Debug
+
+ This causes all communication with a connected
+ device to be dumped to the console from which
+ {application} was started. If you've started it from
+ an icon or menu entry, the output will simply
+ be discarded. This mode can be useful to debug
+ various serial communication issues.
+
+==== Font size
+
+ Selects the set of fonts used in the flight
+ monitor window. Choose between the small,
+ medium and large sets.
+
+==== Look & feel
+
+ Switches between the available Java user
+ interface appearances. The default selection
+ is supposed to match the native window system
+ appearance for the target platform.
+
+==== Menu position
+
+ Selects the initial position for the main
+ {application} window that includes all of the
+ command buttons.
+
+==== Map Cache Size
+
+ Sets the number of map 'tiles' kept in memory
+ while the application is running. More tiles
+ consume more memory, but will make panning
+ around the map faster.
+
+==== Manage Frequencies
+
+ This brings up a dialog where you can
+ configure the set of frequencies shown in the
+ various frequency menus. You can add as many
+ as you like, or even reconfigure the default
+ set. Changing this list does not affect the
+ frequency settings of any devices, it only
+ changes the set of frequencies shown in the
+ menus.
